[Sequence of the N-terminal end of the periplasmic glutamine binding protein of Escherichia coli K12. Comparison with other periplasmic proteins].

The amino-terminal end of the glutamine binding protein of E. coli K 12 has been sequenced (40 residues). Homologies with other binding proteins are shown. Likeness is slightly better with the ribose binding protein and with the leucine, isoleucine, valine binding protein.
